Abstract

By using a deformed Broglia-Winther nuclear interaction potential in the framework of the WKB method, the near- and above-barrier heavy-ion-fusion cross sections of O16 with some lanthanides and actinides have been calculated. The effect of deformed surface diffuseness on the nuclear interaction potential, the effective interaction potential at distinct angle, barrier position, barrier height, cross section at each angles, and fusion cross sections of O16+Sm147,Nd150,Sm154, and Er166 and O16+Th232,U238,Np237, and Cm248 have been studied. The differences between the results obtained by using deformed surface diffuseness and those obtained by using constant surface diffuseness were noticeable. Good agreement between experimental data and theoretical calculation with deformed surface diffuseness were observed for O16+Sm147,Sm154,Er166,U238,Np237, and Cm248 reactions. It has been observed that deformed surface diffuseness plays a significant role in heavy-ion-fusion studies.
